2 Delta Marine Consultants Delta Marine Consultants (DMC) was founded in 1978 for the purpose of providing consultancy, project management and engineering design services to clients on a worldwide basis. The company has expertise in the fields of urban infrastructure, large-scale transport infrastructure, ports and harbour development and coastal engineering. DMC holds strong links with the construction industry through its parent company, the Royal BAM Group. This contributes to the ability to provide solutions to practical problems and to blend innovation with reliability in design. DMC has been rebranded into BAM Infraconsult and is working under that name in the home market. DMC is still used as a trade name for international projects and referred to as such in this Design Capability Statement. DMC has well over 300 employees working in various offices worldwide. The head office is in Gouda (the Netherlands) and apart from several other offices in the Netherlands, local offices are also located in Singapore, Dubai, Jakarta and Perth. DMC is or has been active in a great number of other countries on project basis, often together with BAM contracting companies. Our Core Business Port and Harbour engineering together with Coastal engineering form the core business of DMC. As Port projects are generally associated with substantial economic interests, DMC s clients in this field of expertise include governments, port authorities and large international companies in bulk and containerized cargo shipping who are preparing their port and berthing facilities for future demands. Studies are therefore characterised by an exploration and substantiated selection of viable concepts to meet the functional requirements. This process requires a close co-operation with our clients and sets challenges for our engineers to use their creativity for the development of economic and practical solutions. An in-depth knowledge and understanding of the local conditions is required to arrive at these economic and practical solutions. Local conditions such as wave climate, wind, currents and subsoil characteristics have a considerable if not decisive impact on the most appropriate concept and design. DMC has in house expertise to evaluate the relevant local meteorological and oceanographic conditions, as well as the response of moored vessels. All this expertise is required to develop tailor made port layouts. DMC s expertise in the field of ports and harbours further extends to in-depth knowledge on the design of maritime structures. Conceptual, final and detailed design of quay walls, jetties, offloading facilities, breakwaters and intake and outfall systems are included in the portfolio of DMC. Page 2

3 Client Orientated Approach The often demanding projects related to infrastructure development require a genuine understanding of the clients needs and strategies to support and facilitate decision making on the most economic approach in view of capital investments and life cycle costs. DMC, through its close involvement in construction projects of its sister companies, is constantly challenged to develop the safest and most cost effective solutions. In that technical details are transferred to straight-forward solutions, striving to reduce construction risks to a minimum. Due to the wide experience and the interdisciplinary approach by DMC, valuable input can be provided from concept stage to construction design. Design quality monitoring is carried out at various levels and includes expert panel meetings in particular for multifaceted projects and/or innovative designs. DMC staff is familiar with the relevant international standards and guidelines, including the oil and gas industry and related classification societies. Lead engineers actively participate in national and international work groups of engineering associations to aid in the advancement of engineering practice and to remain at the forefront of its development and knowledge. Regular advanced training is provided in-house, supplemented by external seminars to increase knowledge and expertise focussing on new standards and latest scientific developments. Ports and Harbours, What We Offer DMC offers the full range of port development studies and marine engineering as e.g. Port Studies Layout studies Wave penetration studies Navigation and access Downtime studies (metocean) Mooring and berthing analysis Concept, technical feasibility and due diligence studies Dredging and land reclamation Marine Engineering Quay wall design (sheetpile, cofferdam, diaphragm walls, etc.) Jetty and dolphin designs Sea locks Ship repair facilities Revetment designs Oil and gas terminals Bulk terminals Bollard and fender designs Pile drivability and capacity assessment Vessel wave/ current/ wind interaction Scour protection Damage assessment Technical advice during construction/ Site supervision Page 3

4 International Experience DMC has been involved in projects on all continents of the world; regions include North and South America, Africa, Asia, Middle East, Australia and Europe. DMC maintains a steadily growing overseas office strategically located in Singapore, efficiently cooperating with DMC branches in the Netherlands and servicing clients in the region independently. In 2013 a new DMC branch has opened in Jakarta to serve the increasing number of large projects in the area. Most recent branch openings are in Perth, Australia and Dubai, U.A.E. All DMC offices work closely together, and facilitate the formation of international project teams to best suit project demands. DMC arranges for frequent exchange of staff throughout the organization for training purposes, to benefit from each others work methods and to familiarize with colleagues and cultures. We liaise with skilled partners to complement expertise and local knowledge as required to maximise the benefits for our clients. Tools and Software In order to provide valuable design input data for our projects and to enable a rapid analysis of various design alternatives, DMC uses reliable and state-of-the-art modelling and analysis software packages. As an example, our coastal team uses MIKE 21 suites to investigate waves, winds and currents on site and to assess erosion and sedimentation risks of coastal and riverine areas and in ports. The effects of waves, wind and currents on the moored ship behaviour (either single or multiple vessels) can be assessed using TERMSIM or ANSYS Aqwa. The latter package can even be used to model the dynamic response of caissons, gravity based foundations or any other floating developments. For geotechnical assessments, among others PLAXIS is used to analyse deformation and stability of soil structures. Our structural engineering teams use finite element packages STAAD.Pro and Scia Engineer to analyse and design complex steel and concrete structures. These and other modelling and analysis software packages provide insight into the complex conditions and the structural responses, which enables DMC to come up with founded integrated infrastructure solutions. In order to visualise our designs and the expected construction sequence and schedule to our clients and to identify possible clashes in early stages, DMC has several software suites available for 3D and BIM modelling, such as MX, Civil 3D, ADT, Revit/Autocad, Navisworks and Viz.

6 Universal Terminal, Singapore Client: McConnell Dowell SEA PentaOcean JV Universal Terminal (S) Ltd is a major storage and trading hub on Jurong Island in Singapore with marine facilities catering for the full range of tankers from bunker barges to VLCC s. Having previously been involved with the client at the feasibility stage, DMC was employed to prepare the detailed design of the jetties. The jetty structures comprise of nine berths in total. The works further incorporated two access trestles including pipe-racks and a firewater pump platform as well as a crash barrier. The structures are built in water depths ranging from 15 to 33. Extensive use was made of pre-fabricated elements to increase quality and decrease the amount of work over water. On the land side a quay was designed with 3 additional berths. The bulk of the design work was performed to a very tight schedule over a 9 month period and concurrently with construction activities in progress. This work was followed with design support during further construction. Maasvlakte, the Netherlands Client: Port of Rotterdam West of Rotterdam, the Rotterdam harbour area was extended as part of the extensive reclamation project called the Maasvlakte 2. In the first stage of the development of the Maasvlakte 2, two container terminals were to be realised. Each terminal was to be provided with a deep water quay, fit to accommodate the largest new generation container vessels, and a smaller barge/feeder quay. DMC prepared the tender design for the quay walls and the detailed design (fit for construction). The scope for DMC included four quay walls for the two containers terminals on the newly reclaimed Maasvlakte 2. Page 6

Hazira LNG Port, India Client: Shell Global Solutions DMC was asked by Shell Global Solutions to carry out the design for an offshore LNG/bulk port development at Hazira, Gujarat, India.

The lay-out of the port consists of a dredged basin including an LNG jetty, an LNG terminal platform, and a future bulk storage area, protected by the main breakwater and a lee spur.

during the model tests. Additional tests were carried out to verify the dynamic stability of the rock protection of the LNG terminal platform during construction.

7 Hazira LNG Port, India Client: Shell Global Solutions DMC was asked by Shell Global Solutions to carry out the design for an offshore LNG/bulk port development at Hazira, Gujarat, India. DMC was responsible for the co-ordination of hydrodynamic, nautical and logistic studies and for the physical breakwater model testing. The lay-out of the port consists of a dredged basin including an LNG jetty, an LNG terminal platform, and a future bulk storage area, protected by the main breakwater and a lee spur. The port is connected to the mainland by means of the North and South causeway and a corridor. 2D and 3D physical model tests were carried out to verify the stability of the breakwater, consisting of Accropodes. The stability of the toe was verified, the required lower levels of the front and rear artificial armour was determined, and wave transmission through and over the main breakwater was established during the model tests. Additional tests were carried out to verify the dynamic stability of the rock protection of the LNG terminal platform during construction. Tema Port, Ghana Client: BAM International for Ghana Port and Harbours Authority The deep water berths on the North and South sides of Tema Port s No. 2 quay were to be extended due to the increasing size of modern container vessels. BAM International was awarded the design and construct contract in DMC developed the conceptual and detailed design for this extension. The project consisted of building three new quay walls connected to the existing quay in a U-shaped layout and backfilling the enclosed area. The walls were gravity walls of precast concrete blocks with a cast-in-situ concrete capping beam and an underwater concrete foundation on the seabed consisting of solid rock. Page 7

Eemshaven, the Netherlands Client: BAM Civil for Groningen Seaports At the Eemshaven near Delfzijl, the Netherlands, a similar structure as the Euromax was constructed, but with an inclined

The scope of work included the design, construction and maintenance of three new quay walls, quay areas, prime seawall, scour protections and back filling with dredged sand.

Monrovia, Liberia Client: BAM International for APMT The new wharf at Freeport of Monrovia berths bulk and container vessels with different kinds of cargo.

8 Eemshaven, the Netherlands Client: BAM Civil for Groningen Seaports At the Eemshaven near Delfzijl, the Netherlands, a similar structure as the Euromax was constructed, but with an inclined combi-wall. The quay wall in the Wilhelminahaven (located in the Eemshaven) had to be extended on request of Groningen Seaports in order to improve the logistics of NUON en RWE. The scope of work included the design, construction and maintenance of three new quay walls, quay areas, prime seawall, scour protections and back filling with dredged sand. The total length of the new quay walls is 800m with a retaining height of approximately 20m. Monrovia, Liberia Client: BAM International for APMT The new wharf at Freeport of Monrovia berths bulk and container vessels with different kinds of cargo. The wharf includes a terminal area suitable for various types of cargo handling equipment. DMC s scope included the design of the quay wall with tie back anchors, including drainage systems. The combi-wall with a concrete coping had a length of 600m and a retaining height of approximately 20m. The execution was challenging as operations on the quay wall, which was to be replaced, had to continue. The construction of the quay wall was phased in three sections of 200 meter each to minimize the interference with the ongoing port operations at the old wharf. Maximum vessel sizes were 85,000 DWT, LOA 224m with 32m beam. The initial dredging depth was -12.0mCD. However, a future dredging depth to -15.0mCD was accommodated for in the design. Page 8

Dikkowita Fishery Harbour, Sri Lanka Client: BAM International for Ministry of Fisheries and Aquatic Resources The new Dikkowita Fishery Port serves as an operation base and for sheltered berthing of

5mMSL at the breakwater head. The breakwater is protected by Xbloc armour units.

9 Dikkowita Fishery Harbour, Sri Lanka Client: BAM International for Ministry of Fisheries and Aquatic Resources The new Dikkowita Fishery Port serves as an operation base and for sheltered berthing of approximately 500 fishing vessels up to 40m in length. The new port basis encloses an area of about 14ha protected by the two breakwaters of a total length of 1200m with a maximum water depth of -7.5mMSL at the breakwater head. The breakwater is protected by Xbloc armour units. Geotechnical and structural design of all marine facilities, comprehensive numerical modelling involving wave transformation, sedimentation and wave penetration studies were carried out. As the new breakwaters were situated on top of an existing steep sandstone reef, detailed assessments of the local conditions were required. 2D physical model tests were performed at the DMC wave flume in Utrecht, the Netherlands. DMC also provided assistance and supervision of 3D testing at LHI in Sri Lanka. Contact Delta Marine Consultants (Headoffice) H.J. Nederhorststraat 1, 2801 SC Gouda P.O.
