    Sembcorp Marine, DNV GL, SIMTech and NAMIC sign MOU

    Sembcorp Marine, DNV GL, A*STAR’s Singapore Institute of Manufacturing Technology (SIMTech) and National Additive Manufacturing Innovation Cluster (NAMIC) today signed a Memorandum of Understanding (MOU) to develop disruptive applications in additive manufacturing, drone and digital twin technologies that could revolutionize solutions for Singapore’s offshore and marine (O&M) sector and boost its global competitiveness.

    The quadripartite collaboration will focus on the following three developmental areas with promising potential to bring about transformational improvement to the O&M sector:

    Laser Aided Additive Manufacturing (also known as 3D Printing) for fabricating large-scale ship structures

    Sembcorp Marine, DNV GL, SIMTech and NAMIC will collaborate on developing and certifying Laser Aided Additive Manufacturing technology in fabricating large-scale structures for newbuild vessels. To be funded by NAMIC, this nine-month-long project will take off by end-2017. The project involves a test-case and user-acceptance from Sembcorp Marine, with DNV GL and SIMTech assuming the roles of process certifier and technology provider respectively.

    The project aims to gauge the feasibility of adopting Additive Manufacturing to produce reliable and cost-competitive components locally to support Sembcorp Marine’s offshore and marine construction work. Through this collaboration, DNV GL will be able to enhance the qualification process of Additive Manufacturing and support NAMIC in developing an Additive Manufacturing ecosystem within Singapore’s O&M sector.

    Drones for close-up ship inspection

    Sembcorp Marine will provide DNV GL with the test-bed and user-acceptance for developing close-up ship structure inspection by drones. Complementing surveyor inspections, drones are especially advantageous for carrying out surveys requiring close-up inspection at height or in dangerous and relatively inaccessible areas.

    The project begins later this month. Among other outcomes, it aims to build Sembcorp Marine’s capabilities in drone-based inspection of ships and rigs, while facilitating DNV GL’s refinement of class rules for drone surveys.

    Digital Twin for simulation-based optimization of ship design and operations

    Sembcorp Marine will provide DNV GL with the test-case and user acceptance for investigating the use of Digital Twin technology to create a digital replica of an actual ship, and through simulation determine the ship’s specific design and operational requirements for attaining optimal performance.

    Scheduled to start in the first quarter of 2018, the project allows Sembcorp Marine and DNV GL to strengthen their respective know-how on developing Digital Twin solutions and progress further in their digital transformation journey.

    Sembcorp Marine will test-bed the three projects at its flagship Tuas Boulevard Yard. Host to a broad spectrum of offshore and marine construction, repair and upgrade activities, the 108ha integrated facility is ideal for the required developmental work.

    In supporting the projects, Sembcorp Marine Tuas Boulevard Yard augments its role as a living lab for incubating and verifying disruptive applications for the O&M sector.

    Additive Manufacturing (AM) refers to processes used to create a three-dimensional object in which layers of material are formed under computer control. Objects can be of almost any shape or geometry and typically are produced using digital model data from a digital design file.

    AM has been used in manufacturing, aerospace, medical, industrial and sociocultural sectors, enabling it to become a successful commercial technology.

    Laser Aided Additive Manufacturing (LAAM) is a novel additive manufacturing technology which can be utilised for 3D printing. It works by applying a laser beam as heat source with the additive materials melted and deposited onto the surface layer by layer. Compared to other 3D printing technologies, this patented technology has the following advantages – large print size, free form, high printing speed, diverse material adaptability and printing of multi-materials. It can be used to print large components (> 500mm) for sectors such as offshore and marine and aerospace.

    Many offshore and marine structures are complex, difficult to access and therefore time-consuming and costly to inspect. The safety of inspectors is also an important consideration. By applying new digital tools and processes, classification societies such as DNV GL offer drone-assisted surveys of ballast and cargo tanks, cargo holds, jack-up legs and other components of offshore and marine installations.

    Drone surveys have the following advantages:
     Preparation time is significantly reduced, allowing close-up structural inspections to be carried out at short notice;
     Staging is no longer required for visual inspections;
     Rafting is eliminated;
     No risk of damage to tank coatings;
     Safety of surveyors, ship’s crew and other stakeholders involved in the survey is assured.

    Digital Twin is the virtual image of an asset such as a ship, maintained throughout its lifecycle and easily accessible at any time. By integrating data from multiple sources, Digital Twin provides advanced predictive analytics that yield powerful analyses, insights and diagnostics on the asset’s optimal design and performance.

    Among other applications, Digital Twin is useful in the pre-commissioning of ships.

    The usual commissioning procedure is for the vessel to be built and then commissioned during sea trial. With the Digital Twin, it is possible to pre-commission the vessel prior to actual construction by integrating vendor data into a single consolidated virtual ship for testing.

    The Digital Twin allows the testing of an integrated system in a virtual realm, compared to individual component-testing that can only be done during commissioning. This reduces costly errors and rework.
