GB/T 11869-2018Shipbuilding and marine structures -- Deck machinery -- Towing winches for deep sea use (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 11869-2007 "Ocean marine towed winch".

This standard has the following technical changes compared with GB/T 11869-2007.

---Modified some terms, increased the terms of nominal speed, discharge load, intermediate winch, two-sided winch, waterfall winch (the first Chapter 3, Chapter 3 of the 2007 edition);

--- Added schematic diagram of single-roller winch on both sides and double-roller waterfall-type winch on both sides (3.2.6, 2007 edition 4.1);

--- Increased roll load is 100kN,.200kN, 320kN, 560kN, 2500kN, 3000kN, 3500kN, 4000kN, Basic parameters of 4500kN, 5000kN, 6000kN winches (Table 1, 2007 edition Table 1);

---Modified the roll load is 160kN, 250kN, 400kN, 630kN, 800kN, 1000kN, 1250kN, 1600kN, Some basic parameters of the.2000kN winch (Table 1, 2007 edition Table 1);

--- Modified the requirements for the calculation of the locked load and the load stress of the drum (4.2, 2007 edition 5.2);

--- Removed the requirements for load limiting devices in design and operation (2007 version 5.3);

--- Increased the requirements for load alarm devices in design and operation (4.3);

---Modified the requirements for the diameter of the reel in the reel design (4.5.2, 2007 version 5.5.2);

--- Revised the requirements for the flange height of the reel in the reel design (4.5.5, 2007 version 5.5.5);

--- Removed the requirement for the rope arranging device in the auxiliary equipment (2007 version 5.6.1);

--- Increased the requirements for the console and its layout in the auxiliary equipment (4.6.1);

--- Increased the requirements of the emergency release test in the acceptance test (6.4);

--- Increased the product nameplate requirements (7.3).
