General
Application
This Guide is applicable to non-self-propelled displacement hulls that operate as drilling tender barges, as
defined in Subsection 1/5. Requirements for column-stabilized or self-elevating drilling tender units are
addressed separately in the ABS Guide for Building and Classing Mobile Offshore Units (MOU Guide).
This Guide addresses only the requirements specific to drilling tender barges. The ABS Rules for Building
and Classing Steel Barges (Barge Rules) are to be complied with in addition to the requirements contained
herein.
3
Classification
The conditions of classification are contained in the separate, generic ABS Rules for Conditions of
Classification (Part 1).
3.1
Notation
Drilling tender barges complying with the full requirements of this Guide will be classed and distinguished
by the notation À A1 Drilling Tender Barge.
Barges complying with the ABS Guide for Building and Classing Accommodation Barges (Accommodation
Barge Guide) may be assigned the classification À A1 Drilling Tender, Accommodation Barge.
However, the actual assignment of the Accommodation Barge notation is optional for drilling tender
barges.

Stability
In assessing the stability of drilling tender barges, the requirements in Section 6 of the Accommodation Barge
Guide are to be complied with.
When large cranes are permanently installed, the barge is to satisfy the intact stability requirements in 5-33/9 of the Barge Rules.
3
Pipe Racks
Pipe racks, including the reinforcements for the hull, are to be designed to adequately resist the load effects
of drill pipes or risers imposed on the pipe rack using the design load calculations in 5-3-4/5.5.2 of the
Barge Rules, with the allowable stresses defined in 5-3-4/5.5.3 of the Barge Rules.
Consideration should also be given to the barge in damaged conditions, where the pipe racks are to withstand
the load effects caused by the trim and heel of the barge with a factor of safety of 1.0.
5
Hazardous Areas
Drilling tender barges may have permanent or temporary equipment on deck that creates hazardous areas.
If any of the tender’s intended modes of operation include hazardous equipment, arrangements are to be
made to accommodate and operate such equipment safely. The area where such equipment will be installed is
to be considered hazardous, and electrical equipment, ventilation, and access to adjacent spaces in this area
are to be in accordance with 4-3/11 of the MOU Guide.
Alternatively, if the area where temporary hazardous equipment will be installed is not in compliance with
this Guide, a procedure for making this area suitable for such equipment is to be developed.
7
Mooring Equipment
Owner requested position mooring equipment notations or position mooring system certification are to be
in accordance with Section 10 of the Accommodation Barge Guide.
9
Piping System Segregation
Piping systems carrying non-hazardous fluids are to be segregated from piping systems which may contain
hazardous fluids as per 4-2/1.3 of the MOU Guide.
11

Fire Protection and Operation Safety
General Requirements
In general, the level of safety requirements applied drilling tender barges is depending on the number of
people being carried onboard.
1.1
36 or More Persons
Where a drilling tender barge is fitted with facilities to carry 36 or more persons, it is to comply with all of the
requirements contained in Part 3, Chapter 5 of the Barge Rules.
1.3
Fewer Than 36 Persons
Where a drilling tender barge is fitted with facilities to carry fewer than 36 persons, the requirements
contained in Part 3, Chapter 5 of the Barge Rules are given special consideration, taking into account the
length of the voyage, area of operation, number of persons onboard, and other relevant information. At a
minimum, this will include consideration for the selection of materials for accommodations, service spaces
and work spaces, fire-extinguishing equipment, electrical power supply, lifejackets, lifebuoys, survival
craft, communications, etc.

Other Fire Protection Requirements
In addition to the requirements in the above Subsection 3/1, drilling tender barges are to comply with the
following requirements.
3.1
Passive Fire Protection of Accommodation Block
The exterior boundary of an accommodation block is to be an “A-60” Class boundary for the whole of the
portion that faces the adjacent drilling unit and is within 30 m (98 ft) of any area where a hydrocarbon fire
may arise. If the distance is more than 30 m (98 ft), but less than 100 m (328 ft), an “A-0” Class boundary
is required.
Where an “A-60” Class boundary is required, an “A-0” Class boundary used in conjunction with a water curtain
system designed to provide a density of at least 6.1 liters/min/m2 (0.15 gpm/ft2) of the exposed surface area
may be used as an equivalent means of meeting the “A-60” Class rating.
The ventilation inlets and outlets as well as other openings in the deckhouse and superstructure exterior
boundaries are to be located as far away from the adjacent drilling unit as practicable.
3.3
Active Fire Protection Systems and Equipment
The active fire protection requirements of Part 5, Chapter 2 of the MODU Rules are to be apply; special
consideration may be given taking into account the installed equipment, number of persons onboard, and
other relevant information.
3.5
Fire Protection for Mud Processing Areas and Mud Tanks
If the drilling tender barge is fitted with mud processing areas and mud tanks, additional fire protection is
required in accordance with the ABS Rules for Building and Classing Mobile Offshore Drilling Units
(MODU Rules) as detailed in Section 3, Table 1 below:
