Series 60 Certified For Hazardous Offshore Duty.
Detroit Diesel Corporation(DDC) has introduced what the company billed as the first electronically controlled diesel engine certified for use in hazardous offshore environments. The new version of the venerable Series 60 engine features a specially engineered explosionproof DDEC IV electronic control system. The engine was conceived to meet the stringent demands of offshore petroleum production facilities and other potentially dangerous settings where sparks or high surface temperatures could cause an explosion hazard.
The engine was unveiled at the Offshore Technology Conference (OTC) in Houston, Texas.
The Series 60 DDEC offshore engine is currently available with ratings of 400 hp at 2100 rpm or 450 hp at 2100 rpm, both with 1550 lb.ft. peak torque at 1200 rpm, and 500 hp at 2100 rpm with 1650 lb.ft. peak torque. The six-cylinder, in-line engine has a bore of 5.1 in. moving through a 6.3 in. stroke for a total displacement of 12.7 L.
A 600 hp version is scheduled for availability during the fourth quarter of this year, and DDC sources indicated that the company has plans to apply the new technology to the 2000 series engines by year-end.
The DDEC TV control system equally meets North American, European and Asian hazardous environment certification requirements. Its components have been certified by Underwriters Laboratories (UL) and NEMKO according to various UL, CSA and CENELEC standards for operation in both Class I Division 2 and Group II Zone 2 locations for all gas groups. Certifications also include EPA Nonroad, Euro Nonroad and IMO. The engine is CE labeled.
The certified DDEC system, when used in conjunction with recently developed water-cooled external components, creates a package that is fully certified for hazardous environment operation by Det Norske Veritas (DNV). Engine packages shown at OTO included cooling kits from both Pyroban and Flame Tec.
The DDEC offshore series is the newest addition to the DDC Series 60 line, which has seen a decade and a half of on-the-job use in on-highway, construction and industrial, gas compression, gen-set and marine applications. At OTO, DDC showed the new engine alongside an early Series 60 engine that had seen more than 40,000 hours of trouble-free operation, one of more than 180,000 engines the company has sold into the petroleum market.
