3. TASK GROUP REPORTS & DISCUSSIONS

A. TG1 Task Group on Drilling and Well Servicing Structures – Shawn

Firenza

TG1 2015 June Conference meeting minutes were approved.

API 4F: API 4F, 4th Edition was published January 2013, and is effective August 1, 2013.

Item 6102: Implementation of AISC 2005 Specification.

Marcus McCoo has agreed to chair this work group going forward.

At the June 2016 Conference, the Workgroup met and Marcus McCoo presented

the current status of the SES (Stress Engineering Services) Phase II study.

Within the WG, there is still quite a bit of concern about the load factors being used

in the LRFD methodology. The WG discussed whether to allow both Allowable

Strength Design and LRFD, or that the standard should only allow for one

methodology. SES clarified why they are focused on LRFD instead of ASD to

complete the current study. The Stress engineering report (Phase IIA) will be

reviewed once published and a path forward will be determined.

{Note by SC8 chair: the Phase II study originally budgeted by SES was split into

two separate funding requests. The first request (labeled as Phase IIA for clarity) for

fiscal year 2015 was approved and contracted and is expected to complete in July

2016. The second request (labeled as Phase IIB for clarity) for funding in 2016 has

been submitted and approved, but contract has not been let yet. SC8 chair will work

with API staff to seek approval for funding. The work scope under this request

includes the completion of work on models 2 and 5.}

Ongoing agenda item.

Item 11101: Inclusion of Rig Moving systems in API 4F. .

At the June 2016 Conference, the work group met to review and revise the suggested

wording for the Annex. Anthony Mannering agreed to chair the work group with

support from Sean Duncan. During the work group meeting it was determined that

we need to define Rig Moving to allow us to exclude rig moving load cases from the

1/3 increase. New verbiage was developed and recommended for presentation to

TG1 for a possible ballot.

TG1 reviewed and discussed the draft. The TG agreed with the current proposal for

the definition of Rig Moving and the revisions to 8.1.2. Further work is required in

B.7.1 to adequately distinguish between rig moving and transportation. TG1

approved sending the draft back to the WG for further work.

Item 1402: Wire Rope design factors for setting Blowout Preventers (BOPs).

Mikael Pederson is the chair of this WG.

At the June 2016 Conference, Mikael Pederson presented to TG4 regarding WG

progress. No meetings were held this year but correspondence was held via phone

and email. There has not been much feedback to facilitate progress for this work

item. The WG is looking for more volunteers from the operators group.

Andrew Roskey suggested raising the design factors for all wire rope usage. After

discussion, TG4 adopted a motion to modify the scope of the work item to include

review of design factors for all wire rope addressed in API 9B in addition to the

original scope for setting BOP’s with the main hoist. Mikael Pederson agreed to

continue as chair of this WG under the new scope. A number of additional persons

were added to the WG.

SC8 discussed the expanded work scope and concluded that expanding this work

item greatly increases the audience for this subject, and TG4 should solicit input and

assistance beyond current volunteers. Katie Burkle offered to facilitate drafting and

soliciting other committees for input. Robert Urbanowski suggested contacting

IADC for contractor input; Rhett Winter with IADC volunteered to solicit support

within IADC.


Seconded by: Dennis Fetter

Motion: Accept the expanded scope of item 1402 to include review of all

design factors within RP9B

ballot in 2016.

At the June 2016 conference, SC8 discussed this work; it was noted that a

Recommended Practice will be needed for installation, operation, maintenance and

inspection of hammer unions. The current draft is available to be viewed by SC8

members by requesting access through Katie Burkle. A request was heard to have an

open TG5 meeting prior to sending the specification to ballot; the SC8 chair agreed to

contact Cindy Taff on this subject.

Dr. Nagy expressed a concern that design validation and other requirements are not

included in the current specification, they may need to be added into a next revision.


F. TG6 Task Group to review and make recommendations concerning SC18:TG3

Status Report of 23-Jan-2014 and its potential effects on SC8 licensees

Page 15 of 17


SC18:TG3 was originally charged with the task to “develop a definition for a

manufacturer”; this scope was expanded to include “Have a study conducted and

recommendations made on the appropriate licensee classifications which

organizations should be qualified per a given specification, i.e., assembler, steel

manufacturer, etc.”

At the June 2015 conference, the task group’s work was presented. SC8 directed

TG6 to develop a draft of minimum manufacturing requirements for one SC8

specification; spec 8C was selected and a new work item opened in TG3. The work

product was sent to letter ballot. Ballot 3737 was issued, passed and comment

resolution begun when the SC18 initiative was suspended and TG3 put the ballot

resolution on hold.

SC8 acknowledges that TG6 completed its task and expressed its appreciation to the

WG and its Chair Bo Creek for its expeditious work on this issue.

Motion by: Bo Creek


Motion: Disband TG6 WG as its work is completed.


G. Report from SC18/MPB Liaison (Shawn Firenza)

8. NEW WORK ITEMS (NWI) PROPOSAL REVIEW & APPROVAL

As discussed in the above TG reports.

9. RESEARCH FUNDING – Report by Katie Burkle (API Staff)

SC8 TG1 has a current funded project with Stress Engineering (SES) underway (phase

2, first part of item 6102).

SC8 noted the request from API to delay funding for new projects unless it is a safety or

critical issue. At this stage the July report from SES should include the type 2 rig mast,

but the type 5 may not be included and may require additional funding for completeness

of this work item. Funds for the completion of phase 2 budgeted for 2016 ($40,000)

have been approved, but the contract has not been released. The SC8 chair agreed to

bring up this issue at the CSOEM funding meeting on 6/30/16 and at the CSOEM

regular meeting on 7/1/16. A new contract needs to be resolved with Stress.

Discussion was held regarding a request for funding to perform:

Mapping of sections 4 thru 8 of 8C vs 7K (40%),

Making recommendations (50%) to TG2 and TG3 chairs regarding consistency

of requirements, and

Working with TG2 and TG3 on specification changes (10%);

A notional budget of 10K was proposed.

SC8 chair recommends that Mark Sibille would be an excellent choice for the

work. The person will report to the TG2 and TG3 chairs.



Motion:

Request API funding of 10,000 to assist in mapping,

recommending and expediting specification revisions to align

requirements of 7K and 8C.


10. OTHER NEW BUSINESS

SC 20 is developing standards for critical components which will affect how we qualify

critical components such as castings for example. Katie Burkle agreed to send to the

SC8 chair a summary of all SC 20 work items and work item scopes for distribution to

SC 8 through the my committees website. It was suggested that a number of these specs

be reviewed as personal research, especially for those that may be of value to SC 8, for a

decision on how to leverage these specs in the future.

Page 17 of 17


SC21 had its first meeting earlier this year. Their charge is to review material-related

issues that affect the industry. The SC scope can be accessed in the API MyCommittees

website.

A concern was expressed by that there is no specification for drawworks braking

components, which are arguably some of the most important components in drilling

operations, for brake manufacturers to abide by. Several types of brakes should be

considered. It was expressed that it would be good to get feedback from DNV and brake

manufacturers.

Motion by: Faisal Yousef


Motion: TG2 shall direct its Drawworks WG to consider requirements for

brakes use in Drawworks duty and to draft a NWI as appropriate.
