Wijsmuller wins Yemen SPM contractNews // July 28, 2000
The Ash Shihr terminal handles crude originating inland. This is piped to the terminal storage tanks from where it is pumped to loading tankers at the single point mooring buoy (SPM) located three miles offshore.
The crude is normally destined for ports in the Far East. The SPM is capable of handling the largest of tankers and regularly receives vessels of 300,000 dwt.
The Wijsmuller contract, which commenced on 1 June, involves the provision of a specialist multipurpose support vessel, a line-handling tug, operation of a pollution control vessel and maintenance of the SPM both above and below the water.
During loading operations, which can last for more than two days, the multipurpose vessel Riyan (5,331bhp) attaches a towline to the stern of the tanker to hold her clear of the SPM.
The line-handling tug Al Hami delivers personnel and equipment to the tanker and then handles the hoses during the berthing operation.
Local operating conditions can be particularly difficult during the south-westerly monsoon, which normally lasts from June till October.
The new contract requires the maintenance divers to be based offshore. Riyan has a diving compression chamber aboard and her facilities have been upgraded to accommodate a total crew of 19 including 5 divers. The water depth, at 45m, is within the limitsof air diving.
Both vessels provided by Wijsmuller for the contract underwent modifications to meet CanOxy's contractual requirements.
The 70 tons bollard pull Riyan now has an A frame on the stern deck and a side crane to perform lifting work at the buoy.
She also has two additional winches to allow the deployment of concrete block moorings because of the relatively poor holding ground. A pusher bow is included and a twin diesel rigid inflatable boat (RIB) has been provided for the transport of personneland stores.
The 1991 built Al Hami, a 21m, 17 tons bollard pull line-handling tug, is configured to handle hoses and to take an A frame and winch unit to perform plough dredging.
Both tugs are named after villages local to the CanOxy Yemen Terminal.
Fifty-five personnel are employed on the contract to enable 24 hour per day, 365 days per year cover. Thirty-eight of this number are Yemeni nationals with the majority having been employed at the terminal since its start-up in 1993.
In Yemen, Wijsmuller will utilise its experience of SPM and offshore terminal operations gained in Europe, West Africa, the Middle East, South America and the Caribbean.
The group has been involved in the SPM market since 1980.
