EXECUTIVE SUMMARY
ISO 19905-1 “Petroleum and natural gas industries – Site-specific assessment of mobile
offshore units – Part 1: Jack-Ups” has been developed from SNAME bulletin 5-5A
(SNAME), but has undergone significant modification in structure, and some content change,
during its development. Before 19905-1 will be released as a Draft International Standard
(DIS), it will be necessary to ensure that the document is both complete and produces results
that would be expected. As a first step to achieving this, a three-phase scope of work has
been developed to give an overall understanding of the benchmarking process. The purpose
of the Phase 2 study is to undertake a complete quantitative check of ISO methodology to
verify that the results are in reasonable compliance with SNAME T&R 5-5A Rev. 3, and to
assess possible areas that may have room for misinterpretation
Four separate consultants are to study four different jack-ups, as shown in Table 1-1.

Table 1.1 – Overall Scope of Work
The assessment has used adjusted leg-to-hull connection stiffness and other generic
parameters of KeppelFELS B-Class jackup units. The results presented herein are for the
purposes of benchmarking alone and are not representative of KeppelFELS B-Class jackup
units.
The work performed by Bennett & Associates (BASS) was as the secondary reviewer of the
proposed guidelines, with Global Maritime (GM) and GL Noble Denton having final say on
the various alignment points for the work on the 116C and the B-Class jack ups, respectively.

DESCRIPTION OF THE KFELS B-CLASS JACK-UP
The KFELS B-Class jack-up has three triangular, tubular reversed ‘K’ trussed legs with split
tube, double-sided rack chords. The legs of the unit are guided through the hull by rigid
guide structures located at the base of the hull and at the top of the elevating system. The
unit has twelve (12) pinion gears per leg for elevating the hull. A Self-Positioning Fixation
System (SPFS) is used to support the unit when elevated.

STRUCTURAL MODELLING
The global and detailed response of the unit under static and environmental loads was
evaluated by performing a detailed Finite Element analysis of the structure and foundation.
The capacity of the unit was assessed based on Ultimate Limit State methodology as
described in the ISO 19905-1, (i.e., factored loads and factored ultimate capacities). The
effects of hull side-sway (P-delta) and dynamic amplification were included in the analysis.
A detailed structural model of the leg and of the surrounding supporting structure was made
using SACS finite element software. The assumptions made in the Finite Element (FE)
structural modeling are described below.
 The leg chords were modeled by beam elements with appropriate shear and bending
properties. The axial stiffness contribution of the rack teeth was ignored in the
strength assessment; however, 10% of the rack tooth area was assumed in the global
response calculation. Braces were also modeled as tubular beam elements.
 The jack frame was modeled by beam elements with appropriate section properties.
The leg guides were modeled by spring elements with freedoms in the appropriate directions
giving reaction forces corresponding to guides reacting against the rack teeth.
For LeT 116C Jack-up the pinions were modelled in a similar fashion giving the appropriate
restraint and stiffness.
For KFELS B-Class Jack-up the Self-Positioning Fixation Systems (SPFS) were modeled in
a similar fashion giving the appropriate restraint and stiffness. Figure 2.3 shows the KFELS
B-Class Jack-up SACS Finite Element model. Figure 2.4 shows the LeT 116C Jack-up
SACS Finite Element model.

CALCULATION OF LOADS
Wave and current loadings at each storm heading were automatically computed using the
SEASTATE Program of the SACS finite element analysis software.
Forces were computed using Morison’s equation and wave particle kinematics based on
Stokes Fifth Order Wave Theory. Wind forces were computed using the formulae and
coefficients given in the ISO 19905-1. The wave and current forces were factored by the
kinematics and blockage factors.
Benchmark Panel instructed that the wave kinematics/spreading reduction factor (Hdet to
Hmax) of 0.86 was to be used for all the cases. To account for blockage effects of the leg, a
current blockage factor has been derived in accordance with the ISO 19905-1. An average
blockage factor (i.e., reduction in current velocity) of 0.91 was used for KFELS B-Class
Jack-up and 0.77 for LeT 116C Jack-up.

DYNAMICS
The inertial loadset is derived from random wave time domain dynamic analysis; two DAF's
are calculated, one for the base shear (BS) and one for the overturning moment (OTM). The
applied inertial loadset included the inertial base shear and the inertial overturning moment.
This is accomplished by a combination of lateral force acting on the hull VCG level and
correcting moment applied as a couple to the hull. 80% of initial foundation fixity was
included in the random wave time domain dynamic analysis.
2.9
HULL SWAY EFFECTS
The combination of vertical (gravity) loads and the side sway of the hull result in a secondary
bending moment (P-delta moment), which is also included in the SACS analysis. The Pdelta moment increases both the vertical footing reaction (due to increased overturning
moment) and the moment at the lower guide due to the offset of the footing induced by hull
sway.

LeTourneau 116C and KeppelFELS B-Class Phase 2 Benchmarking of ISO 19905-1
P-delta effects are included as follows:
P-delta Moment = Hull Weight  Lateral Hull Displacement
The P-delta force is applied at the hull VCG level, giving the correct overturning moment
and lower guide bending moment. This force is calculated as follows:
P-delta Force =
P  delta Moment
Distance from footing to hull VCG
Point loads were added to the hull structure to give the correct hull weight and center of
gravity. The analysis was run twice, first to calculate the hull sway, and then repeated
including the additional overturning moments due to hull sway.

INTERMEDIATE ANALYSIS RESULTS AND COMMENTS
3.1 HYDRODYNAMIC COEFFICIENTS
For all the storm cases, the hydrodynamic coefficients were calculated for the legs in
accordance with the methodology described in the ISO 19905-1. The legs were assumed to
have a marine growth level of 12.5 mm (thickness). Rough and smooth tubular members
were assumed to have drag coefficients of 1.0 and 0.65 respectively.
Rough members and marine growth extends below MSL+2 m and smooth clean members are
assumed above.
The resulting drag coefficients are presented in Table 3.1 and 3.2. Note that the heading
directions are defined as counter clockwise. A 0 degree heading is taken as from stern to
bow.

Bennett & Associates (BASS) and Global Maritime (GM) agreed to use GM’s hull wind
area, which was based on wind test, for this analysis. Global Maritime’s hull wind areas are
given in Table 3.5. All areas include the shape coefficients. The centers of effort (C of E) are
reported relative to the keel. A 0o heading is taken as bow-on, a 90o heading as port-on, etc.

CONCLUSIONS
Although the ISO and SNAME results are similar, this could not have been achieved by the
parties acting independently.
Several checks were made on both units and normalization of results at that point of
calculation were needed to obtain similar results.
There are several areas where BASS feel there is insufficient guidance to achieve the same
level of risk as we would achieve using our methods of normal site assessment using
SNAME RP 5-A:
 Leg to hull connection – relative stiffness of all attachments.
 Chord robustness versus risk during unusual loading.
 Better chord to guide interaction and analysis.
