equipment Hamworthy extends inert gas system backlog
Hamworthy projects include regasification systems for two large floating storage and regasification units building for Höegh at Hyundai Heavy Industries
A contract from Hyundai Heavy Industries calls for Hamworthy to supply an inert gas generator (IGG) package for the QUAD 204 FPSO project, which will be deployed by BP off the Shetland Isles in the North Atlantic as a replacement for the Schiehallion FPSO. The new 270m x 52m facility is designed to produce
130,000 barrels of oil and 2.2 million m3 of gas per day, with a storage capacity of 1.06 million barrels of oil.
Hamworthy will deliver two sets of IGG units, including two deck water seals, two control systems, two inert gas cleaners and two pressure vacuum breakers. The package and control system will be
Bilge water treatment for smaller vessels A lightweight oily water separator introduced by UK-based specialist Victor Marine reportedly weighs 30 per cent less than existing equivalent equipment. The new CS Lite OWS model reduces the oil content of bilge water to under 5 ppm and can be
supplied with processing capacities from 6 to 48 m3/day.
Victor Marine’s CS Lite oily water separator

Comfortably satisfying the IMO’s MEPC 107(49) regulations, the system was developed to meet demands for oily bilge water treatment on vessels where weight and size are issues, such as megayachts and fast attack craft. While a standard Victor Minisep CS0500 OWS weighs 225kg dry, a CS Lite model with the same throughput capacity weighs only 169kg. Weight saving was achieved by using 5083-grade aluminium instead of mild steel for the major structural elements of the new unit, which exploits Victor Marine’s proven three-stage separation process: a hydrophobic high-viscosity removal system; an oleophilic coalescing filter element; and an adsorption granular media polishing stage. A monitor continually ensures that the effluent water quality meets the IMO regulations and prevents illegal overboard discharges. The system is said to be easy to install and operate, and avoids problems associated with the chemicals and membranes of other OWS types. The equipment has Bureau Veritas type approval and can be supplied with various process options to suit specific installations.
located in a dedicated inert gas room for protection from the harsh environment. Other contracts booked last year
covered a fully assembled IG system for delivery in 2012 to the Goliat FPSO, which will operate in the Barents Sea, and systems for the FPSOs Usan and Akpo for deployment offshore Nigeria.
Boiler retrofit benefits Alaskan factory trawler
An 8,000 kg/h capacity MSH steam boiler from Parat Halvorsen of Norway will be retrofitted to replace the original steam-raising plant of the factory stern trawler Northern Hawk, owned by US-based Coastal Villages Pollock. Built in 1990 by the Norwegian yard Ulstein Hatlo, the vessel operates in the Bering Sea harvesting Alaskan pollock.
The boiler installation supplies steam for the onboard fishmeal plant and ship’s heating system, and the replacement plant is specified with the latest technology for burning fish oil. Chevak, Alaska-based Northern Hawk will be docked in Seattle in April this year for the retrofit during a general maintenance and repair project. Parat MSH boilers are of horizontal smoke tube design with steam evaporation in the upper section and a combustion chamber dimensioned for burning marine diesel oil or heavy fuel oil; gas and dual-fuel burners can also be supplied.
Complete compact units are delivered, insulated and pre-assembled with all valves and instruments, burner and control panel. A fully automatic control system is based on electronic controllers and electric/ pneumatic actuators, and all operations ›››
