General information
Oil Tankers are developed for a wide range of main particulars and capacity. Large vessels with a capacity of 300,000m3 or more are under development. The design of today’s oil tankers is generally characterised by a single screw type of vessel with a rather high block coefficient. For this type of vessel, special attention has to be paid to the design of the fore body (bulbous bow), resulting in good wave pattern, a low overall resistance and related good powering performance. Furthermore, an excellent after body design, with a good flow towards the propeller(s) and rudder(s), without flow separation is an important issue.
Large differences between design (loaded) draught and ballast draught have to be taken into account. The combination of single screw type of ship, high propeller loading, and rather pronounced wake field requires carefully checking of the risk for cavitation erosion and vibrations.
Various interesting propulsion plants are possible for oil tankers. Recent research at MARIN included the traditional single screw, podded propulsors and hybrid propulsors.

Services & Activities
MARIN is involved in the development of the hull design, the power optimisation and the cavitation, noise erosion observation.
The seakeeping performance in all weathers and all sea states is tested in our Seakeeping and Manoeuvring Basin and using our numerical tools. Special attention is given to the sloshing loads in the tanks, which can become very high.
The Offshore Department investigates the offloading of LNG from a floating platform to a LNG tanker.
The low and high speed manoeuvrability and controllability can be accessed as well in our basins. Due to the recent trend, in which the fore ship becomes slender and the aft ship full, special attention is needed on the steering capability.
The Nautical Centre MSCN offers training of the crew by simulating approach manoeuvres on a full size bridge. But also Quantitave Safety Assessments of the nautical operations and Real-time simulations are carried out to reduce risks to a minimum.
The Trials & Monitoring Department is involved in full-scale measurements of ship performances, cavitation observation, pulse and loads measurements.
