Wayside. Suite 100 Houston, TX 77087 713-643-1051 Wijsmuller Wins Design Contract For Four 50-Ton-Bollard-Pull Coastal/Terminal Tugs rm The design of the 108-foot by 32-foot tugs for Norwegian shipowners Johannes Ostensjo incorporates on the hook, on the bow, alongside, and push-pull towing capabilities. Towing winches are installed both forward and aft, and the vessels are equipped with an all-around heavy rubber ten- dering. Wijsmuller Engineering, consultants to the marine industry, have been awarded a contract to provide a complete design package for four new 108-foot, 50-ton-bollard-pull coastal/termi- nal tugs for Norwegian shipowners Johannes Ostensjo. The tugs will be of the stern drive type with extensive firefighting and oil pollution control capabilities. They will be used at the Sture/ Mongstand terminals for the handling of tank- ers of 300,000 dwt under adverse weather condi- tions. Building will take place at Batservice Verft A/S, Mandal, Norway. Delivery of the first two tugs is scheduled for May and June 1988.

Downstream pressure of corrosive and non- corrosive liquids and gases can be regulated with the MR10 Series in ranges of 0 to 100,0 to 250 or 0 to 500 psig. A sensitive neoprene diaphragm (on brass versions) or Teflon coated neoprene diaphragm (on stainless steel versions) assure precise regulation. They also utilize an unbal- anced poppet design for dead tight sealing of inlet pressure up to 3,600 psig. The MR10 Series is only AVi inches in length, and in its standard configuration is ready for panel mounting with locking nuts. They can also be equipped with optional pressure gauges, CGA inlet fitting and downstream safety valve for direct use on gas cylinders. Operating temperature can range from — 40 F to +160 F. Flow coefficient (Cv) = 0.18. Bodies are available made of brass or 303 stainless steel with V* -inch female NPT inlet and outlet ports.
