Oil Cargo Tanks News

Wärtsilä will supply its Volatile Organic Compounds (VOC) recovery technology, LNG fuel gas handling systems and the auxiliary engines for two new shuttle tankers being built for Singapore based AET Tankers at the Samsung Heavy Industries shipyard in South Korea. The order, worth in total more than $37 million, was booked in January 2018. The ships will operate on Liquefied Natural Gas (LNG) as the primary fuel, but VOC – the gas evaporating from the oil cargo tanks – will also be utilised as fuel by mixing it with the LNG, thereby reducing the vessels’ bunkering needs. This is made possible by Wärtsilä’s VOC recovery system, which by combining the VOC with the LNG, provides the potential for savings of over 3000 tons of fuel each year per vessel.

A new shuttle tanker concept developed by the world’s largest shuttle tanker services provider, Teekay, will offer a new level of innovation, says Wärtsilä, whose smart technology solutions will be featured on the new vessels. To date, Teekay has ordered four of these ‘next generation’ ships, each to be built at the Samsung Heavy Industries (SHI) yard in South Korea. According to Wärtsilä, the newbuilds will feature a broad assortment of its latest technology innovations, all of which are central to the concept’s overall performance gains.

Two new coatings, Hempadur Quattro XO 17820 and 17870, are being introduced to increase the service life and reduce on-station maintenance requirements of offshore assets by leading worldwide coatings supplier Hempel. The new high-performance pure epoxy uni-primers presented today (9 January), combine excellent corrosion protection with construction flexibility. Hempadur Quattro XO 17820 / 17870 are part of a series of two-component epoxy primer coatings which provide advanced crack resistance using Hempel’s patented fibre technology. They can be applied in immersed and non-immersed areas of any offshore asset, from offshore platforms and drilling rigs through to support vessels.

Bluewater Energy Services B.V. informs it was awarded a contract from shipbuilder Hyundai Heavy Industries (HHI) for the engineering, procurement, construction and integration (EPCI) of a turret and mooring system for a floating production, storage and offloading (FPSO) vessel to be part of the Chevron-operated Rosebank project on the edge of the U.K. continental shelf. At about 80 meters in height, with a process manifold/turntable of about 34 meter in diameter, the turret and mooring system will be among the largest ever designed and built, Bluewater said.

Sophisticated they may be, but the designs of today's LNG, LPG and ethylene carriers are in reality based on the simple parameters of the ideal gas laws governing the relationships between pressure, temperature and volume. In addition, the materials in direct contact with the cargo must be matched with the properties and characteristics of the cargo. The key to the designs is the atmospheric boiling temperature of the cargo, i.e. ambient for fully pressurised LPG, -33 deg. C for anhydrous ammonia, -48 deg. C for propane, -104 deg. C for ethylene and -163 deg. C for LNG. In terms of fleet numbers the total number of gas ships is small compared with oil tankers, general cargo ships or passenger vessels.

In late August of this year the Dubai Drydocks delivered a handsome 45-metre lube oil tanker to Gulf Agency Company of the same city. The vessel, named GAC Mumtaz was built to a design from Mr. G.S. Chopra of Seatech Solutions in Singapore. With a beam of 12 metres the boat will carry up to six TEU (20-foot equivalent unit) containers in addition to three 50 cubic metre lube oil cargo tanks. Other tankage includes 60 cubic metres of fuel and 20 cubic metres of water. The steel fabrication materials for the hull and superstructure plate ranges from eight to eleven millimetres. The 3.5-metre moulded depth of the hull is built with a double skin and bottom for added safety. Accommodation is provided for ten people.
