STS Hose is a cold-resistant marine Ship-to-Ship transfer hose designed for offshore operations in low-temperature and Arctic-class environments. Engineered with a flexible synthetic rubber inner tube formulated to maintain elasticity under sub-zero conditions, it combines high-tensile textile reinforcement layers and a steel wire helix structure that ensures dimensional stability during both suction and discharge operations.
The outer cover uses weather-resistant marine elastomer compounds to protect against seawater, ice abrasion, UV exposure, and long-term thermal cycling. This hose is specifically developed for cold-region offshore logistics where conventional hoses often fail due to stiffening, cracking, or loss of flexibility.
A North Sea offshore supply operator faced serious operational delays during winter fuel transfer operations between supply vessels and offshore platforms. Standard hoses became rigid at low temperatures, increasing handling difficulty and causing delayed connection times during bunkering operations.
After switching to Hongruntong Marine cold-resistant STS Hose, the operator achieved stable flexibility even under sub-zero conditions. Hose handling time was significantly reduced, and coupling alignment became safer and faster. Over a full winter operational cycle, fuel transfer efficiency improved by 24%, while deck handling incidents related to hose stiffness were eliminated.
