1 Scope

This recommended practice provides clarification and guidance for implementing the

Expanded Ship Work Breakdown Structure (ESWBS) weight classification system. This

guidance provides a common weight system that transcends all ship classes. Therecommended practice will provide a static classification system based on the original

1985 ESWBS document and the current dynamic database. This document does not

replace ESWBS for historical weight keeping. The purpose of this document is to

incorporate weight classification changes due to changing technology, construction

practices, and other issues as they arise.

2 Purpose

There is a need for guidance on the use of the current weight classification processes and

practice. Currently there resides a different weight classification system for different ship

classes based off of the 1985 ESWBS document. The current database for weight

classification is available only online and does not contain detailed descriptions for

weight classification. Additionally, certain new technologies do not have a home in the

current weight classification system. The purpose of this document is to provide

clarification for using the ESWBS weight classification system in a static form that

includes details.

To correctly catalog new technologies additional weight classification is need in order to

ensure commonality between ship classes. Some technology can be classified under the

current structure, requiring only additional definitions to be added to the current system.

Additional groups are necessary to accommodate other technologies. To accommodate

new technologies, this guidance has re-titled groups, created groups, and added detailed

definitions to groups. As new technology becomes available additional guidance will be

included to ensure commonality in weight classification.

3 Associated Documents

This optional section should show complementary or other associated documents used

with this RP. This is not a bibliography of citations used within this document; that is

found at the end of the document.

This recommended practice shall be used in conjunction with the following publications.

When the following specifications are superseded by an approved revision, the revision

shall apply.

5 Weight Classification Guidance

This weight classification guidance is to be used for applying weight group classification

to weight line items in a ship weight database. The following section gives specific

guidance on classifying different weight items and systems. All weight items not

specifically described are to be placed in the three digit weight group as dictated by their

function or system they sustain. The 1stand 2nddigit levels are typically reserved for title

cards. Section 5 provides guidance on select systems for clarification purposes.

5.1 Integrated Power System (IPS)

The IPS employs the same power generation for both propulsion and ship power. IPS is

a methodology change from previous ships that have separate systems for propulsion

power and ship service power. Most of the IPS consists of existing technology and parts.

IPS components will be placed in groups based on their function. Historical databases

may need to be adjusted when comparing a non-IPS ship with an IPS ship. The most

notable change will be weight moving from group 2 to group 3 as some of the propulsion

systems will now be combined propulsion and ship service power generation systems.

Dedicated propulsion generators will remain in group 235 as they remain a dedicatedsystem.

5.2 Dual Band Radar (DBR)

DBR uses one array for two different radar search modes. DBR is considered a multi-

function radar and is included in group 456 Multi-Function Radar Systems.

5.3 Electronic Module Enclosures (EME), Rafts, and Skids

5.3.1 EME

Electronic Module Enclosures (EMEs) are designed to be installed as a unit with self

contained environmental and power considerations. EMEs are designed to serve onefunctional group. EME and all of its internal equipment shall be placed in the group that

best describes its intended function. The EME Foundation belongs in group 188

Common Foundations.

5.3.2 Rafts

Rafts are defined as a common foundation that is houses equipment that serves a single

designated function. The weight of the Raft shall be placed with the group to which its

function is best aligned. If a Raft houses more than one function but one single function

remains primary, the weight of the raft will be placed with the group to which its primary

function is best aligned. If a raft serves as a foundation for multiple groups with no

single primary function the weight of the raft and its foundation belong in group 188

Common Foundations. The foundation for a raft belongs in group 188 Commonfoundations.

5.3.3 Skids

Skids are defined as a common foundation which is used to mount multiple pieces of

equipment for multiple functions or systems. Skids are used for ease of production and

equipment mounting requirements. The equipment mounted on the skids may have

individual foundation and dampers that are not part of the weight of the skid. Individual

equipment foundations mounted on the skid shall be placed in the group appropriate to


7/117


7

the equipment. The weight of the skid and skid foundation belong in group 188 Common

Foundations.

5.4 Fiber Optics

Fiber optics is broken down into two separate weight classifications. The fiber optic

cable is treated as cable based on its function. For example; fiber optics cable used forlighting will be in group 331 Lighting Distribution. The second weight classification is

Fiber Optic Cable Plants which includes fiber optic interconnection boxes, trunk cables

and their associated connectors and splices. Fiber Optic Cable Plants belong in group

416 Fiber Optic Cable Plants.

5.5 Total Ship Comput ing Environmental Infrastructure (TSCEI)

TSCEI is a computer infrastructure that contains different systems on the ship. There is

no specific weight group for TSCEI equipment. The equipment for TSCEI belongs in the

group of the system to which they are associated.
